To all lwhom fit may cof/wem:

Be it known thatI, JOHN S. NASH, a citizen of the United States, 'and a resident of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Im rovementsin Tumbler-Washers, of which do declare the following to be a full, clear, and exact description, reference being had to the accompanying drawing, forming part ofthis specification.

he resent invention has relation more paticulitrly to that class of tumbler washers designed for Washing tumblers used at soda Water fountains, and the invention consists in 'the features of novelty hereinafter described, illustrated in .the accompanying drawing and particularly pointed out in the claims at the end of this specification.

Figure l is a view in central vertical section through a tumbler washer embodyin my invention. Fig. 2 is a view in horizonta section on line 2-2 of Fig. 1. Fig; 3 is a view in central vertical section through parts shown in Fig. 1, but illustrating the valve mechanism inclosed position., Fi 4 is an enlarged detail view in vertica section through the spray head or-nozzle. Fig. 5 is: a detail view'showing the upper end of the conical distributer at the top of the sprayv nozzle. j

In theaccompanying drawing, A designates the bowl or vessel that is adapted to set within an opening in the serving counter,- or any other convenient location. The lowerend of the bowl A is suitably secured to 'the top of a coupling B that isprovided with a passage b communicatin with an opening in the bottom of the bowl for the escape of water from the bowl,` and is provided also with an induction channel b through which freshwater will be delivered for cleansing the tumbler.

Within the coupling B, which is preferably a suitable casting,'is arranged an interiorly threaded, vertical flange b" with which engages the correspondingly threaded lower end of a valve casing C, a acking ring b3 being preferabl interposed between the lower end lof the va ve casing C and a shoulder that is formed at the base of the annular flange As shown, the-lower end of the valve Gesing', is interiorly threaded to receive a correspondingly threaded, perforated or open .valve stemsupport D, through the openings in which water will freely pass, :is will presently appear. Through the hub of the valve stem support D passes the` stem e of the valve E, this valve E being conical or fur-l rushed witha conical packing ring that will engage with a valve seat or shoulder c? upon the interior of the valve casing C. The opening ci above the valve seat cis slightly larger than the cylindrical portion @3 of the valve stem immediately above the valve E, and above this portion e3 ofthe valve stem, the stem is reduced as at e so as to allow for the free passage of the water through the valve seat when the valve" is in open position, as

illustrated in Fi 1 of the drawing. The

Vvalve Eis also s 'ughtly smaller in diameter than the cylindrical portion c of the valve casing beneath the seat cz'of the valve. A coil spring F that is interposed between the valve E and thev hub of the valve stem guide D serves to normally hold 'the valve E against -its seat c as clearly shown in Fig. of the drawing. i

A serious objection with valve mechanism heretofore employedin .tumbler Washers of this general ty is, that when the tumbler is suddenly lifte or closed quickly to cut off 'the iow lofwater, there is a tendency of the valve to pound or rebound upon its seat, thus producing a disagreeable noise. Byforming the valve. casing with a contracted cylindrical. portion c5 beneath the valve seat, through which the valve E shall pass as it approaches' the seat c?, the closing of the v ve-is more gradual and all danger of the pounding or l rebounding-of the valve and water hammer in the pipes is avoided. And this is overcome in a measure, also, -by pre- .viding the enlarged portion e3 of the valve stem, which ortion enters the opening through the va veseat e. as the valve closes against itsseatl In other words., thev gradual restriction of theflow of water, as-the valve isslowly seated, effectively, serves to prevent the pounding or rebounding-of the Vvalve whenit reaches its seat.

The uiper ortion' of the valve casing C is provide Wit threadedl openings in which are fitted threaded ends of the angular spray tubes G, these spra `tubes being preferably four in number an arranged to extend u wardly as shown, ad'acent the wall of t e bowl- .Each offt e spray tubes Gr` is formed with a plurality o f transverse, in-

soV

` tion against the exterior of the tumbler H to be cleaned. y l

The upper end ofthe valve casing C is interiorly screw-threaded to receive respondingly threaded end of a cap K that is perforated to permit the tubular portiorrE vof the valve stem to slide freely therethrough.

This tubular portion E of the valve stem is provided at its base with lateral channels e that communicate with achamber-at the upy#per end, of the lvalve casing 0./ rIhe top of the tubular extensionrlll7 Aof the .valve stemis screw-threaded to :receive the threaded h'ub m of the tumbler-'support M., this "support comprising a plurality of arms m that are covered lwith rubber tubesfm2 tumbler H will bear, as shown-in Fig. 1 of the drawing. From the top 'of' the hub mot the tumbler support projects ithe f s ray-head through which water will be delivered to cleanse the interior of the tumbler I-I. As shown7 this spray-head com risesa casing formed of a lower part; anupper part N, the lower part N having a tubular, contracted portion that is screw :igrreaded to engage the hub m of the tumbler support, and the two parts N and N are connected toether by a threaded joint, as clearly shown 1n the drawing. Within the spray.- head casing is mounted a distributer P that is provided with a plurality of open ended, spiral channels p that will serve to impart a swirl `to the water as it passes through the opening fn in the capuor upper portion N of the casing, and into t 's opening n preferably projects an extension p that rises from the top of the distributer P.

When the washer is in normal or idle position, the parts will occupy the position shown in Fig. 8 of the drawing, at which time the valve E will serve to completely cut off the How of water. If, now, an inverted tumbler H be placed upon the` tumbler support M and be ressed downward so as to compress the coi spring F and force the valve E and arts to the position shown in Fig. 1 of the rawing, the water will flow"throu h the valve casing and will be distributed y the s ray tubes G over the exterior of the tumler. At the same time the water will )ass through the spray-head or nozzle and, y reason of the spiral channels of the distributer I), will be caused to ass in a swirling film against the interior ci) the tumbler, and this action will continue so long as the tumbler is held in the depressed position shown in Fig. l. When the pressure on the tumbler is re lieved, the parts will resume the normal osition shown in Fig.' 3 of the drawing. Eby imparting a swirling movement to the water issuing from the s ray-head or nozzle, a much more thoroug cleansing of the intethe cor-v or similar sof-t'V .materiaL against which the edgev of the` emes? rior of the tumbleris effected, not only 'because of the more complete and uniform dis' tribution of the water over the interior of the tumbler, but also because of its being thrown in a spiral course against and around f the interior of'the'tumbler. ,'So, also, when the valve is allowed to close in order to lcut off the iow of water throu h the valve casing,

the action is such that al pounding or rebounding ofthe valve is avolded.

While I describe what I regard as the preferred form of m r invention, I do not wish tge invention to e understood as restricted t the recise details of construction above set forth), as these may be varied without fleparture from the scope of the invention.
